"l To all whom it may concern: Y*

part of this specification,

Be it knownthat I, O'i'ro L. E. WEBER, a'citizen ofthe United States, resident'of St. Cloud, countyof Stearns, State of Minnesota, have invented certain new and useful Improvementsin Trucks, of which the following is a specification. l

This case is led as a division of my pending application, Serial No. 295,770, iled May 8, 191.9.v The object of this invention is to provide means for handling a cylindrical object, such as a roll of paper, in a vertical position, provision being made for gripping the object through the hole or opening in the center thereof. A y

Other objects of the invention will appear from the following detailed description.

. The'invention consistsy generally in various constructions and combinations, 'all as hereinafter described and particularly pointed out inthel claims. k

In the drawing, 10 represents'the horizontal frame orbas'e of the truck, having truck wheels 11 and platform 12. TheV motive vsectional view on the line 5-5 view ofthe truck, as

V`Vpower for the truck is preferably furnished by `storage battery and electric motor, not

shown, mounted on the rear of the platform and within ysuitable vreceptacles 13 and 14. A switch 15 is provided for convenience in starting and stopping the motor, andwires 16 connect the battery with the motor. The hoistingdrum 17 is mounted on suitable standards 18'a11d is vdriven from the motor through apinion v19 on the motor shaft 20. A Gear-'21 on the counter shaft 22 is arranged in lbearings 23 on onerside of the standards and has a worm 24 meshing with a wheel 25 that is rigidly Vmounted on theA hoisting d rumv 17, The drum may lbe rotated in Specification of Letters Patent.

either direction by a suitable device, lnot shown, but included Vin the Velectric circuit. The hoisting frame preferably consists of upright bars 26 having channels rigidly secured to the base 10 and-rigidly held by means of braces 29. Y Y "i The channel bars 26 are connected at the top byza transverse yoke 31 which prevents spreading of the bars and at the same time provides room for passage of the hoisting carriages. An auxiliary hoisting carriage comprising the vertical channel bars 32 and the lower horizontal cross bars 33 and 34 and the upper cross bar 35 is arranged to slide in the channels of the bars 26 anda main hoisting carriage 36 has guide rollers 37 adapted to travel in the channelsV 38`of the bars 32. i

Sheaves 39, 40 and 41 are mounted in the carriage 36 and sheaves 42 and 43 are mounted respectively in the lower cross bars 34 andthe up er cross bar 35 of the auxiliary carriage. in the yoke 31 and a chain or cable 45 passes from the hoisting drum 17 over this sheave, thence under the lower sheave 42 and over the upper sheave 43 and then down under the sheave 41 in the main carriage, -as shown in Fig. 1. This arrangement of the cable is particularly adapted, as above set forth, to handle the cylindrical rolls in a vertical position. The arrangement to handle the cylindrical rolls in a horizontal position isfully disclosed in the co-pending application, and it need only be here mentioned that, when it is desired to handle the rolls in a horizontal position,the cable 45, after passing' over the upper sheave 43 passes down under sheaves 39 and 40 in the mainA carriage, instead of Vunder the sheave 43, as herein described and shown in Fig. 1.

A hook 46 is secured to the end ofthe cable for attachment to a sliding, clamp` ing bar 48 (see Figs. 1, 3 and 6). The hoisting carriages normally rest on the base 10. The roll of paper, represented by numeral 50, is held in a Msaddle or cradle 51 attached to the main carriage v.36 and having arms 52 partiallyV embracing the roll and connected by rods V53 and 54.V The cradle is detachably connected toa swiveled block 55, preferably by means of dovetailed or slotted grooves nLthe block in which enter tongues on the cradle, resting against a suitable stop as at 57. The swiveled block 55 Aforms a part of y are to behandled vertically or tiered onel 3()` the hoisting carriage 36 and is mounted in -terloclring annular flanges 58, 59 and 60. The

sheave 39 is mounted in the main carriage andthe sheave 40 in the block 55 and the location of the sheaves is such that the cable 45 passing under both sheaves is directly in the center of rotation of the block. The sheaves 39 and 40 are used only when handling rolls inthe horizontal position or lip-ending rolls into vertical position. In these operations the upward Atravel of the main carriage, from 'itsabove stated normal position on the base 10, provides sufficient elevation for such vhandling of the roll. But, when rolls in a vertical position are to be handled, as when loading cars, the cable is removed from the sheaves 39 and 40 and brought under the sheave 4l at the top ofthe auxiliary frame and the hook 46 is attached tothe clampingbar 48. 'This bar is provided with a downwardly turned arm 61 adapted to enter thecoreopening in a roll and the bar will slide horizontally in guideways 62on aplate 63 that is detachably secured `to the cradle Iarms 52 Vby suitable means, .as lugs 64, and screws or pins 65. When the rolls upon the other, the plate 63 and hook 46 are attached, as described, and the carriage is hoisted to the proper position with respect to the roll, as in Fig. 1. In this figure, the carriage 36 is shownas having been raised to the upper limit of its independent travel whereat its upper ends have contacted with the upper cross bar V35 of. the .auxiliary hoisting'cacrriage and the vertical channel bars 32 of the auxiliary ,hoisting 'carriage have been upwardly moved in the channel of the bars 36. The amount of ,travel ofthe auxiliary carriage is indicated by the height which thelower horizontal cross bar 33 has beenmoved from the horizontal base 10 of the truck. AAfter the carriage has been hoisted to the properposition with respect tothe roll, as in Fig. 1, the cradle is then lowered to drop the clamping .bar 48 into thecore opening h, as indicated lby dotted lines, and as the hoisting drum isagain reversed to Vhoist the roll, the first effect is to clamp the roll tight against the cradle and a continued hoisting raises theroll to the desired height, as in Fig. 3, forV placing it on the top of another roll. ,In Fig. 3 the auxiliary carriage (and, therefore, the main carriage) is shown las having been raised toa much greater height thanthat shown ,inFigs. l and 2, in order that theroll 50 may be placed upon the upper end'of `another vroll. y 1 Forthe purpose of adapting'lthe hoisting vtruck Imore readily for handling :rolls 'of different, sizes in a vertical ,position fand'to enable one man to handle both Vthe :truck proper and the hoisting device, I prefer to Vconstruct the clamp bar48, as shown in Figs.

justableon the bar 48 by means of a slot 69 and secured by 'a bolt 70. At its inner end the bar is provided with a transverse notch 7l into which a lockingfinger 72-of a pivoted latch 73 is adapted to enter for the purpose of temporarily locking the bar against movement while the plug 68 is inserted into the core opening of the roll. The latch 7 3 has an arcuately curved nose which normallyprojects through an aperture in the plate 63 as is shown in dotted lines in Fig. 4. When the core plug 68 is lowered into the core opening 501 of the roll 50, the projecting nose of the latch is upwardly thrust by contact with the roll 50. This upward thrust is sufiicient lt'o cause the finger 72 of the latch to be withdrawn from the notch 71 of the bar 48. This disengagement of the latch 7 3 is effective to allow the bar to be moved lengthwise to draw the roll against the cradle at the beginning of the hoisting operation. In Fig. 4, this latch 73 is shown in full lines as raised to agreater height than it is raised by contact with the roll 50. The latch 7 3 has been illustrated in such abnormal position in order clearly to permit accurate representation in this figure of the relative position ofthe notch 71 in the bar 48.
